The MULTI-PROCESS SWITCH has two sets of out-
put terminals. You connect the wire feeder unit cables
to the set of terminals on the left side of the box and
the stick or air/carbon arc cables to the set of termi-
nals on the right side (facing the front of the machine)
as shown in Figure C.1. The output terminals are pro-
tected against accidental contact by hinged covers.
When the MULTI-PROCESS SWITCH is in the "Stick
or Air/Carbon Arc" position, only those terminals are
energized. The wire feeder nozzle or gun and elec-
trode are not electrically "hot" when in this mode.
Follow these steps to install the MULTI-PROCESS
SWITCH:
1. Confirm that the IDEALARC® DC-600 VRD
POWER ON/OFF switch is in the OFF position.
2. Disconnect main AC input power to the IDE-
ALARC® DC-600 VRD.
3. Open the terminal strip hinged cover located on
the Case Front Assembly.
4. The MULTI-PROCESS SWITCH is mounted to
the case front with four 1/4” self-tapping screws.
The screw holes are 13.8” apart side to side and
4.5” apart top to bottom, Run one of the 1/4”
screws part way in and out of the screw holes to
open them up. Make sure that the two sleeved
control leads do not get pinched when hanging
the switch; route them out the side to the right of
the switch. Support the switch in position and start
the four screws, then tighten them.
5. Route the MULTI-PROCESS SWITCH control
leads through the strain-relief box connectors and
into the terminal strip. Connect wire feeder control
cable as specified in specific connection diagram
and make other terminal strip connections as
specified on the connection diagram for the
Lincoln wire feeder being used.
6. Connect the control leads from the MULTI-
PROCESS SWITCH to terminals #2 and #4 on
the IDEALARC® DC-600 VRD's terminal strip.
7. Connect the right cable from the MULTI-
PROCESS SWITCH (facing the front of the
machine) to the IDEALARC® DC-600 VRD posi-
tive (+) output terminal. See Figure C.2.

8. Connect the left cable from the MULTI-PROCESS
SWITCH (facing the front of the machine) to the
IDEALARC® DC-600 VRD negative (-) output ter-
minal. See Figure C.2.
9. Connect the wire feeder electrode and work
cables. See Figure C.2.
• Insert the wire feeder electrode and work cables
through the strain relief loop on the left side of the
IDEALARC® DC-600 VRD (facing the front of the
machine).
• Connect the wire feeder electrode and work
cables to the electrode and work
terminals on the left side of the MULTI-PROCESS
SWITCH.
10. Connect wire feeder control cable and make other
terminal strip connections as specified on the
connection diagram for the Lincoln wire feeder
being used.
11. Set the IDEALARC® DC-600 VRD OUTPUT
TERMINALS switch to REMOTE.
